yes, I've seen posts on this very forum that tell you how to do this and they also add that you should then put the mud flap on the front of the tire as to break the air up before it hits the tire. I don't recall where it is though.

John is a cool Dude, lives a few miles away from me. I've met him at one of his free workshops for saving energy at home.. I'd love to get to know him better but he is a very busy man.

Statler: Wake up you old fool. You slept through the show.Waldorf: Who's a fool? You watched it.

I tried this myself in another topic here and found no difference. The Leaf needs a little more research and some serious mods to make it better for high speed travel with better aerodynamics. The best and cheapest I've seen so far for the Leaf are full wheel covers and the back wheel bridge cover if you really want to maximize your aerodynamics.

You can really get down to splitting hairs with this business of aerodynamics. If adding mudflaps degrades range, then opening a window should really blow your range all to heck. It doesn't - but perhaps it makes some small difference. Too many things to obsess about.

Simply put, mudguards are an aerodynamic hindrance. And of course the faster u go, the more detrimental their effect. I took mine off because they were fugly and and aero issue. I would like a rear wheel arch cover. I could make something stupid out of cardboard and tape it on, but scientifically, due to changing conditions and living in a highly populated area...would be hard to get any remotely scientific data. It is understood by many on the Honda Insight forum (I own an original Honda Insight also) that the rear wheel covers are only good for about 1 maybe 2 mpg at best.
